Title: Tracking error detector for optical head
Inventor: OKAMOTO TAKEZO
IPC: G11B7/095
Filed: 1991-12-06
Abstract: PURPOSE:To provide the tracking error detector for which an entire optical disk device is miniaturized, the degree of freedom for design is improved and a seek operation can be easily executed in any direction excepting for a radial direction without adding complicated structure, etc. CONSTITUTION:A seek axis is offset from a prescribed radial axis passing through the center of an optical disk. Since a photo-detecting means to detect light reflected from the disk is arranged while being inclined only at a prescribed angle on the center side of the disk in respect to a direction parallel to the prescribed radial axis passing through the center of the disk, the seek axis of the optical head can be set without being limited in the radial direction of the disk, and it is not necessary to add the complicated structure. Therefore, not only the window of a cartridge can be effectively used but also the degree of freedom for designing the seek axis of the optical head at a drive device can be improved.
